ANN ARBOR, Mich. – Ricky Stanzi threw his third touchdown pass to Derrell Johnson-Koulianos early in the fourth quarter and Michael Meyer kicked a 30-yard field goal with 2:53 left, helping No. 15 Iowa hold off Michigan for a 38-28 win Saturday.
The Hawkeyes (5-1, 2-0 Big Ten) led the Wolverines (5-2, 1-2) by three TDs early in the fourth quarter for the second time during the game.
Tate Forcier came in for Denard Robinson and threw a 45-yard pass to Junior Hemingway and his 3-yard run made it 28-21 with 6:55 to play.
Iowa's Adam Robinson, who scored twice, converted a third-and-8 at the Michigan 40 by breaking a tackle on a 26-yard reception to set up the victory-sealing kick.
Denard Robinson left during the third quarter after he was hit hard on a run, but it wasn't immediately clear if he stayed on the sideline because he was hurt or simply ineffective for the second straight week.
He was 13 of 18 for 96 yards with an interception — an ill-advised heave into coverage — and a TD. He ran 18 times for 105 yards.
Forcier, who started every game last year, was 17 of 26 for 239 yards with two TDs and two interceptions.
Stanzi completed 17 of 24 passes for 248 yards with three TDs and no turnovers.
Adam Robinson ran for 143 yards and two TDs.
The most important statistic, though, was the turnover margin, won 4-0 by the Hawkeyes.
Michigan got off to a good start by forcing a three and out, scoring, and forcing another three and out.
Then, the Wolverines fell apart. They're hoping the same thing doesn't happen to their season for the second year in a row.
Michigan has lost two straight after opening 5-0. It flopped to a 5-7 finish last season after winning the first four games.
When the Wolverines weren't getting overmatched physically by Iowa, they hurt themselves with mental miscues that led to a slew of penalties.
The Hawkeyes, meanwhile, avoided mistakes and their sound brand of football set up another win.
Iowa has won 20 of 23 games and 22 of 26 since the 2008 season.
Two years ago, Rodriguez lost a school-record nine games in his debut with college football's winningest team and signs of progress since then have been stunted by a lot of losses, many of them ugly.
